My wife told me she had slept with another man last summer. I was upset of course but i accepted the truth about until i found out that they became friends on facebook. We had been having problems leading up to this point and she had been having some issues. She left and got a place her own of her own in september. We have been together for 17 years and have three children together. She resumed her relationship with the man she had told me about in in the summer. I got temporary custody of our children and she received after school visitation with no overnights. In december i made an effort to reconcile and she told me she was pregnant and in love with this OM. I had a vasectomy after our last child and i am sure that it is not mine!!! I am not so sure that she wanted to get pregnant. In january she stated that she still loved me and wants to work this out and we have been to counseling twice.(she also was convicted of a dui in jan) She has had no contact with the OM for 2 weeks but i am sure he is wanting to be involved with this child. I love my wife and don't want our kids to have a broken home. How do we tell them that their mother is pregnant from another man? I am mainly contemplating this for our children. If OM gets courts involved will this child carry his name? A baby from this affair is enough but this OM being involved has me concerned for the long term. Should I try to make our marriage work or is it damaged beyond repair?
